DISK WHEEL.

Application ilcd .August 7, 1922. Serial No. 580,067.

To all whom z't my concern.'

Be it known that I, HARRY W. KRANz, a citizen of the Unitedl States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Disk Wheels, of 'whichtheiollowing is a full, clear, and eX- act description, referencebeing-had to theaccompanying drawings.

This invention relates generally to disk wheels and more particularly toa disk wheel employed in connection with a tire carrying rim permanentlyconnected to the periphery of the disk, the object being to provide asimple. and inexpensive connection between the rim and disk, and anotherobject is 4to employ in connectionfwith a sheet metal disk v a tirecarrying rim having a central depressed portion into which the tire beadcan be projected at one side of the rim in order to clear the tire vbeadfrom the opposite side of said rim. i

With these various objects in view the invention consists in the novelfeatures of construction and in the manner oficombining or arranging thesame, all of which will be fully described hereinafter and pointed outin the claims.

In the drawings' forming part of this 30 specification Fig. 1 is asideview of a portion of a disk wheel embodying one form of myinvention; Fig. 2 is a sectional view on the line 2-2 of Fig. 1; and Fi3 is a sectional view showing a slight y modified mode of attachment,

In carrying out my invention I employ a one piece tire carrying rimhaving the side .flanges 11 andthe base portions 12, the tire beadsresting 'upon the base portions 12 when the tire is inflated. The rim isalso formed with an inwardly projecting portion 13 arranged centrally ofthe base portions 12 and of such depth that the tire bead can be pushedinto the same at one side of the rim when it is desired to remove thetire bead from the opposite side of the rim. This tire carrying rim 10is not'only in-one piece but is not divided at any point nor is itprovided with any separable tire engaging rings or langes.

In connection with this tire carrying rim I employ a sheet metal disk 15wh1ch at its center may be of any suitable shape' 'for connection tothehub of the wheel body. At

its periphery it is bent as shown at lii.

order to engage the inner side of the base portion 12 and the angle ofthe diskwith reference 4to the liange portion 16 is such that the diskwill irmly contact with the side of the inwardly projecting portion 13of the rim. The periphery of the disk and the rim are united by means ofrivets 17 which pass through the disk and depending portion of the rimand the rivets 18 which pass through the flange 16 and the base portion12 and it will be noted that these rivets 17 and 18 alternate as mostclearly shown in Fig. 1.

It will also be understood that the disk can be connected to either sideof the rim according to the inclination of the disk. In Fig. 3 I haveshown a slight modification of themanner of attaching lthe disk to therim and in this instance the disk 15 isfirst.

the rim is increased and also placed at a point closer to the plane oft-he wheel.

The disk wheel constructed as herein shown and described can be madedemountable at the hub if 'so desired or it can be permanently connectedto the hub` and the tire shoe detached from the rim bydeflating the tireand pushing in the bead at one side and thereby clearing the bead at theother side 'from the rim.

Having thus described my invention, what I claim is:

1. The combination with a tire carrying rim having an inwardlyprojecting base portion and spaced tire bead seats upon opposite sidesof said inwardly projecting portion, and a disk having a lateral periheral fiange,'said flange being secured to t e inner face of the beadseat ortion of the rim, the adjacent portion of t e disk being connectedto the adjacent wall of the inwardly projecting portion of said rim.

2. In a wheel the combination with a disk having a laterally turnedperipheral edge, of a tire carrying rim having an inwardly projectingbase portion and a' laterally extending portion, the angled edge of thedisk seating in the angled portion of the rim and means for uniting `therim and disk.

3. The combination with a tire carrying rim having an inwardly extendingbase portion and spaced tire bead seats upon opposite sides of said baseportion, and a disk having circumferentially extending radially spacedoffset portions, the outerof said offset portions ybeing secured to theunder side of one said tire bead seats and the f vinner of saiil offsetportions being secured to the bottom of said base portion.

4. The combination withy a tire carrying rim having an inwardlyextending base portion and spaced tire bead-seats upon opposite sides ofsaid base portion, and a disk having ciroumferentially extendingradially spaced oset portions, the outer of said offset portions beingsecured to the under side of one of said tire bead seats and the innerof said offset portions being secured to the bottom of saidbase portion,and the radial portion of the disk between the circumferential offsetportions being connected to the adjacent Wall of the inwardly projectingbase portion of said rim.

In testimony whereof, I liereunto aiix my signature. i
